Big Turn Music Fest

I'm sorry, but I do not have sufficient reliable knowledge about an organization or event specifically named 'Big Turn Music Fest.' It's possible that it is a local or relatively new event that hasn't received widespread coverage in major databases or publications by October 2023. Without additional distinguishing information or context, such as its specific location or notable participants, I'm unable to provide a detailed description.
